How B2B Operators Approach iGaming Vendor Due Diligence

An iGaming operator runs on vendors it does not control. Its game content comes from studios and aggregators. Its platform, payments, KYC checks, odds feeds, and fraud tools are usually built by other companies. When one of those partners fails an audit, loses a license, or goes offline on a big match day, the operator takes the hit with its regulator and its players.

For this reason, experienced B2B operators treat vendor due diligence as a core risk function and not as paperwork. Here is how they usually run it.

1. Start With the License, Then Verify It

A vendor's regulatory standing is the first filter. Operators confirm three things:

• The right licenses for the right markets. A supplier licensed in Malta is not automatically cleared to serve players in the UK, Ontario, or a regulated US state. Many regulators require B2B suppliers to hold their own license or registration, so the vendor's coverage has to match the operator's target markets.

• That the license is active. Operators check the regulator's public register directly and do not rely on a logo in a sales deck.

• Enforcement history. Past fines, warnings, or suspensions show how the vendor behaves under pressure.

A vendor that is vague about its licensing gets a firm answer quickly: no.

2. Check Certification and Game Integrity

For content and platform providers, fairness has to be proven by an independent party. Operators ask for:

• RNG certification from accredited test labs such as GLI, BMM, iTech Labs, or eCOGRA

• Game-level certificates for each target jurisdiction, since certification is often market specific

• Published RTP values that match the certified math

• A clear process for how game updates are re-tested before release

If a game version live on the operator's site differs from the certified version, the operator is the one exposed. Good operators ask how the vendor controls versioning, not just whether certificates exist.

3. Know Who You Are Actually Dealing With

Corporate due diligence covers the people and money behind the vendor:

• Ultimate beneficial owners (UBOs) and key directors

• Sanctions and PEP screening on the company and its owners

• Adverse media checks for links to fraud, money laundering, or unlicensed markets

• Group structure, including any sister companies that supply grey or black markets

That last point matters a lot. Many regulators expect licensed operators to avoid suppliers that also serve unlicensed markets. A vendor's other clients can become the operator's compliance problem.

4. Assess Financial Stability

A cheap vendor that goes under mid-contract costs far more than an expensive one that stays solvent. Operators review:

• Audited financial statements from recent years

• Revenue concentration (does one client account for most of the business?)

• Funding position and runway for younger companies

• Any history of disputes over unpaid revenue share or jackpot liabilities

For jackpot and wallet providers in particular, operators want to know how player funds and prize pools are protected if the vendor fails.

5. Test the Technology, Not the Pitch

Technical due diligence is where most sales claims are tested. Operators look at:

• Uptime and SLAs. Historical uptime data, incident reports, and what penalties apply when targets are missed.

• Scalability. How the system handled peak events like major tournaments or promotional spikes.

• Security. Standards such as ISO 27001, PCI DSS for payment vendors, and results from recent penetration tests.

• Integration quality. API documentation, sandbox access, and the real effort needed to go live.

• Data handling. Where data is hosted, whether that meets local data residency rules, and how GDPR or equivalent obligations are covered.

Serious operators run a technical proof of concept before signing. A vendor that resists a sandbox test is telling you something.

6. Review Compliance Tooling

Regulators hold operators accountable for player protection, so vendors must support it. Key questions include:

• Can the platform enforce deposit limits, cooling-off periods, and self-exclusion across all products?

• Does it integrate with national self-exclusion schemes where required?

• Are AML and KYC checks configurable by market?

• Can the vendor produce the reports regulators ask for, in the required format, on time?

A vendor with weak responsible gambling features pushes compliance cost and risk back onto the operator.

7. Read the Contract Like a Risk Document

Commercial terms decide what happens when things go wrong. Operators focus on:

• Revenue share, minimum fees, and how gross gaming revenue is calculated

• Liability caps and indemnities for regulatory breaches

• Audit rights, so the operator can inspect the vendor when needed

• Termination rights if the vendor loses a license or breaches compliance

• Exit and data migration terms, so switching vendors does not trap the business

The best contracts assume that one day the relationship will end, and plan for a clean exit.

8. Ask the Market

Reference checks are underrated. Operators speak with current and past clients of the vendor and ask direct questions:

• How fast is support during a live incident?

• Did the integration timeline match what was promised?

• Were there any surprise costs?

• Would you sign with them again?

Industry forums, affiliate feedback, and conference conversations also reveal patterns that no due diligence questionnaire will catch.

9. Keep Monitoring After Signing

Due diligence does not end at contract signature. Licenses expire, ownership changes, and vendors enter new markets. Mature operators set up ongoing controls:

• Annual or semi-annual reviews of licenses, certifications, and financials

• Continuous sanctions and adverse media monitoring

• Performance tracking against SLAs

• A clear internal owner for each vendor relationship

Many regulators now expect operators to show this ongoing oversight during audits, not just a file from onboarding.

A Simple Framework to Remember

Most operator due diligence programs can be summed up in five questions:

1. Is the vendor allowed to operate here? (Licensing and certification)

2. Who is behind it? (Ownership and reputation)

3. Will it survive? (Financial stability)

4. Does it actually work? (Technology and security)

5. Can we leave safely if we need to? (Contract and exit terms)

Final Thoughts

In iGaming, an operator's compliance record is only as strong as its weakest vendor. Thorough due diligence takes time, but it protects the license, the player base, and the brand. The operators who grow steadily in regulated markets are rarely the ones who move fastest on partnerships. They are the ones who choose partners carefully and keep watching them after the deal is done.
